A very nice home/smalloffice NAS box.

Purchased to act as a home video/music/images repository (for streaming to various DLNA players around the house as well as via SMB share) and a backup host. I fitted it out with 4x Seagate 4TB IronWolf NAS drives (HD-36S-SE) and it hasn't missed a beat.

There isn't a video output - everything is accessible via a web interface. Out of the box it therefore requires DHCP but you can set it to a static IP after the initial configuration. About the only thing I've not been able to set up on it natively is Internet Radio streaming over DLNA (There's a 3rd-party Serviio app which allows this, but it requires Java and is thus a bit on the bloated side).

Speed-wise, it's able to utilize the full speed of its Gigabit ethernet port - For larger file transfers I've been hitting data transfers of 100 MB (note the capital B) per second consistently even whenever it's just plugged into a regular BT homehub. It runs cool and reasonably quiet (you'll hear the disks spinning rather than the fan) and there's an option to dim or turn off the front panel LEDs. By default it'll turn off the disks to save power after 20mins of inactivity. It's yet to have any lockups or crashes after several Terabytes of data going to/from it.
Honestly the only downside is that the drives load from the rear of the unit - so you need to unscrew the back screw to fit/remove them. But if you're not changing disks regularly then that's a non-issue. Would definitely recommend.
